The Timer/Aquastat combination is designed to cycle the circulator during peak demand periods. Use the two devices together or separately. When used together, the Timer switches ON, sending power to the unit. The Temperature Aquastat measures the temperature and cycles the circulator as long as the Timer is “ON.” If used separately, the Timer operates the circulator during the chosen number of 15-minute intervals.

When using only the Aquastat, the circulator cycles continuously to maintain a temperature between 95º F. and 115º F. For maximum convenience and flexibility, you can retrofit both to any Taco 00® Series Cartridge Circulator
